The invention discloses a self-locking lifting structure appliance which comprises a lifting hook body and a locking arm, a lifting hook body is arranged on the lower portion of the lifting hook body, lifting arms are arranged on the upper portion of the lifting hook body, first pin holes are formed in the lower portions of the lifting arms, second pin holes are formed in the upper portions of the lifting arms, and the two ends of a first pin shaft are rotationally installed in the second pin holes of the two lifting arms respectively. The lower portion of the locking arm is a locking hook body, the middle of the locking arm is hinged to the lifting hook body, a third pin shaft is fixedly arranged on the upper portion of the locking arm, one end of the lifting rope is fixed to the third pin shaft, and the other end of the lifting rope bypasses the first pin shaft to be connected with lifting equipment. When a heavy object (bar materials and shaft parts) is lifted, the opening of the lifting hook body and the opening of the locking hook body are close to each other under the action of the pulling force of a lifting rope, so that the heavy object is automatically locked, and when the heavy object is heavier, the automatic locking force is larger, and the safety is higher; the device is flexible in operation, simple in structure and good in universality, and has popularization and use values.
本发明公开了一种自锁吊装结构器具,包括吊钩主体和锁紧臂,吊钩主体下部为吊钩钩体,吊钩主体上部为吊臂,吊臂下部开有第一销孔,吊臂上部开有第二销孔,第一销轴两端分别可转动安装在两个吊臂的第二销孔中,锁紧臂下部为锁紧钩体,锁紧臂中部与吊钩主体铰接,锁紧臂上部固定设有第三销轴,吊绳一端固定在第三销轴上,吊绳另一端绕过第一销轴与起吊设备连接。当吊起重物(棒料、轴类零部件)时,受吊绳拉力作用吊钩钩体的开口与锁紧钩体的开口相互靠近,从而自动锁紧重物,当重物越重时,自动锁紧力越大,安全性越高;本发明操作灵活、结构简单、通用性较好,具有推广使用价值。
